Effects of gelatinized anionic salts in prepartum
diets of dry cows on feed intake, urinary pH,
and serum parameters

Nine multiparous cows were fed diets containing gelatinized anionic salts to determine the effects of acidified diet on dry matter intake (DMI), urinary pH, and serum parameters. Dietary cation-anion difference (DCAD) for precalving diets was approximately +10, -2, and -10 meq/100 g DM, respectively. There were no differences on DMI of cows fed the acidified diet compared with DCAD+10 (P>0.05). Mean serum Ca concentrations were increased for cows fed the DCAD-10 diet (P<0.0001). Urinary pH of cows fed DCAD-2 and DCAD-10 diets were decreased compared with DCAD+10 (P<0.0001). These data indicate that a diet based on reed hay and maize silage supplemented with gelatinized anionic salts with a DCAD value -10 meq/100 g DM is suitable for prepartum dairy cows.
